Abstract

The research investigates the mechanism of microwave radiation effects on biological characteristics and structural-dynamic parameters of a sensor bioluminescence system. The research objects are a sterile growth medium (fish meal hydrolisate) and a bacterial culture. It has been established that irradiation causes changes of the growth medium spectral properties within the range of 200-350nm. Changes take place in the intensity and character of luminescence, as well as in relaxation parameters of nuclear magnetic resonance, growth characteristics of the bacterial culture, its cellular morphology and surface topology. The research results enabled us to establish the mechanisms of primary molecular processes that occur when the bacterial culture is exposed to microwave radiation. Transformation of the dynamic-structural state of adsorbed water phases on biopolymer surfaces has been found to be the key factor in the mechanism of microwave effects on living and water-containing objects.

Main findings

Microwave irradiation was associated with changes in the growth medium’s spectral properties (200–350 nm), bioluminescence characteristics, NMR relaxation parameters, bacterial growth characteristics, cellular morphology, and surface topology. The authors report that transformation of the dynamic-structural state of adsorbed (bound) water phases on biopolymer surfaces is a key factor in the mechanism of microwave effects on living and water-containing objects.
